To all whom it may concern:

Be it known that I, MAIHIAS STAnTLnn, a citizen of the United States, residing Illinois, have invented a eel-min; new and useful Improvement in Metallic S ring- Supports, of which the followi'n'gis'a specification. v

My invention relates to metallic spring supports adapted for beds, ticles, and the like, and the object of the invention is to provide convenient and practical means for mounting'the spring upon metallic cross members in distinction to the ones consisting of webbing, Contributory to this general object it is my -pilrpose to provide means for attaching the base of the spring to the cross members; alsoto, provide cross members which, although made of metal, are resilient Within certain limits so as to give the finished article a springy efiect, in addition to that which is obtained from the coiled springs alone. Another ob ject is to provide means for deadening the sound when the spring closes up.

I obtain my objects by the construction illustrated in the accompanying drawings in which- Figure 1 is a perspective View showing the upholstery spring and the supporting means therefor.

Fig. 2 is a sectional View on the line 2-2, Fig. 1, and

Fig. 3 is a perspective view of. a hook for securing the foot of the spring to the" cross members.

Like numerals denote like parts throughout thesevenal views. I i

In the form selected to illustrate the invention the spring 1 is of the ordinary coiled type sometimes referred to as an upholstery spring and sometimes as a bed spring. The lower turn of the coil rests upon two cross members 2, 3 at the point of intersection thereof. Said cross members, instead of being strips of webbing, duck or other woven fabric, are of metal. In general shape they are in the form of strips somewhat narrower than the fabric strips commonly used for this purpose in beds and upholstery. While thesize is immaterial, I have found by experiment that a strip about 1% to 2 inches wide serves the pur ose to advantage. These strips are arrange crosswise, one set being anchored to the side rails and the other to the end rails of the bed at Chicago, in the county of Cook andfState of m airing the pockets of upholstered arany regular or conventional patterns.

parts is such that "will overlie the strip, will then pass down spring pr frame of the upholstered article in any'suitab'le' manner.

"Iirthe preferred form of invention the strips are not'pcrfectly plain, but are indented with aseries of small pockets which render them resilient lengthwise I Vhile the diameter and depth of the ockets may be varied, alsuitable effect will e produced by such diameter that two, three or four may be arranged between the margins of the strip. It is not neccssa1 however, that these pockets or depressions occur at regular intervals or spool-dingI to he depressions may be formed by hammering orb "dies.

TlielOwer turn of the spring is secured to the crossstrips 2, 3 bymeans of hooks 4., one of which is shown in perspective in Fig. 3. The hooks are double ended, the larger hook 4 lieing" adapted to engage the spring itself, and the smaller hook 4* being adapted to engage the cross strip. For this purpose each cross strip has a series of holes 5 punched therein,spaced at regular intervals. lach hook has an offset 4. between its ends, the result beingthat one portion of the hooks near the larger end 4* will rest upon the top of the cross strips while the other portion will lie beneath the cross strip, and the portion 4" will pass up through one of the apertures 5 and engage the edge of it. In other Words, the construction of the one portion of the hook thrbiigltone o'fthe holes 5, then'pass along beneath the strip until the next hole is rsani-eagwlrereupen the hook 4' will pass up "strengths-1101s and-engage the edge ofthe strip, thus holding the hook securely in place. The holes 5 are of sufiicient dimension, lengthwise of the strip, to permit the lip or hook 4" to be disengaged from the engaged edge. In practice, the larger hooks 4 engage the lower turn of the spring, while the remaining portion of the anchoring device extends thence radially outward along the strip, passing down through the first hole it comes to, thence along underneath the strip to the next hole where the hook 4 passes up through and engages the margin of the hole. When the spring is thus held by four hooks, it will be prevented from moving transversely in any direction. Up holstery springs of any diameter may be employed, for the hooks are adjustable lengthwise of the cross strip and any size may be accommodated. Furthermore the hooks may be so placed as to stretch the "bottom turn of the spring-that is, increase its diameter somewhat above normal.

In some cases it is desirable, in order to prevent the spring from making a noise when the turn next to the bottom closes down on to the support, to fasten a disk 6 of wood, wood fiber, or similar material upon the cross strips. Such a disk ma be fastened by means of a cotter pin or any other suitable means. Ordinarily, it will be slightly smaller in diameter than the diameter of the lowermost coil of the upholstery s ring, and hence will fit within it and at t e same time will form a cushion to prevent the metal of the upholster spring from striking u on the metal of the cross strip. This avoids creating an unpleasant metallic sound when the spring is compressed.

It will be observed that my structure is both durable and sanitary, also that it readily lends itself to quantity production. The structure has another advantage in that it is unnecessary to carry more than one type or size of stri for any and all kinds of beds and upho stered articles, because both large and small springs may be attached by merely adjusting the hooks in the proper holes. Repairs may be easily made because if by any circumstances a stri should become damaged (which is unlike y in view of its durability) that sin le strip may be renewed without particu arly disturbing the rest of the structure.

Having thus described my I claim as new and desire to ters Patent is 1. In combination, a helical bed or upholstery spring, crossed metallic strips for supporting the spring, at least one of, the strips having a row of holes extending longitudinally, and a fastener having a hook at each end, one hook adapted to'engage in a hole in the metallic stri and t e other hook adapted to engage a 001 of the spring.

invention what secure by Let- 2. In combination, a helical bed or up holstery spring, crossed metallic strips for supporting the spring each strip having a row of holes arranged longitudinally, and double ended hooks adapted at one end to engage in the holes and at the other end to engage the lower coil of the spring, said hooks being oflfset between their ends, whereby one portion of the hook may everlie the strip and the other portion underie it.

3. An upholstery spring mounting comprising crossed sheet metal strips having a multiplicity of shallow indentations 1mressed in them, a coiled spring located at he intersection of said strips, the strips having apertures, and fasteners having at one end a hook adapted to engage in one of the apertures in a strip, and at the other end a hook adapted to engage a turn of the spring.

4. n upholstery sprin inountin com prising crossed sheet meta strips, a elical spring located at the intersection of said strips, each strip having two pairs of holes in it, and four double-ended hooks, the outer end of a hook being adapted to engage the outer hole of a pair, and the body of the hook passin through the remaining hole of the pair, an the remaining end of the hook being adapted to engage a turn of the SPIlIli.

5. n upholstery sprin mounting comprising crossed sheet meta strips, a helical spring located at the intersection of said strips, each strip having two pairs of holes in it, and four donb e-ended hooks, the outer end of a hook being adapted to engage the outer hole of a pair, thence pass under the stri to the inner hole of the pair, thence upward through the last mentioned hole, thence in the same direction toward the point of intersection of the strips, and aving a hook at the inner and adapted to en age a turn of the spring.

11 witness whereof, I have scribed my name.
